Continental Contitech 20043047 Timing Belt Xl 85T

Product Description

The CONTINENTAL CONTITECH 20043047 is an XL-series positive-drive timing belt rated for precision synchronous power transmission applications. Constructed from nylon with a fiberglass cord reinforcement, this belt delivers consistent tooth engagement and resistance to stretch under cyclic load. The trapezoidal tooth profile of the XL section is an industry-standard geometry that meshes with corresponding XL-pitch sprockets and pulleys. With 85 teeth and a pitch length of 170.00 mm (belt number 170XL), this belt is suited for light-duty and medium-duty drive systems where positional accuracy and repeatable indexing are required. Licensed HVAC, mechanical, and industrial technicians commonly install this type of belt in blower assemblies, fan drives, and auxiliary equipment drives.

This timing belt is used in synchronous drive applications across commercial and light industrial equipment. Typical installation scenarios include HVAC air-handler blower drives, small conveyor systems, pump drives, and other equipment requiring a no-slip positive-drive connection between a motor shaft and a driven component. The XL belt series is a widely adopted standard pitch, making this belt a common replacement item in preventive maintenance programs for both residential and commercial mechanical systems.

Key Features

• XL-series positive-drive design ensures no-slip synchronous power transmission
• 85 trapezoidal teeth provide smooth, low-vibration tooth engagement
• Nylon belt material offers durability and resistance to abrasion
• Fiberglass cord construction minimizes belt stretch over service life
• Belt number 170XL with 170.00 mm pitch length for easy cross-reference and replacement sourcing

Compatibility

Designed as an OEM-style replacement for synchronous drive systems requiring an XL-section timing belt with 85 teeth and the 170XL belt designation. Compatible with standard XL-pitch sprockets and pulleys per industry drive-design standards.

Installation Notes

Installation is typically performed by a qualified mechanical or HVAC technician. Before servicing, de-energize all electrical power to the equipment and lock out or tag out the drive system per applicable safety procedures. Verify the replacement belt number and tooth count against the existing drive components before installation. Do not force the belt onto sprockets using sharp tools, as this can damage the cord reinforcement and reduce service life.
